Three vegetables you can't finish eating, toss them into potting soil, they'll grow lush and you'll even harvest a little surprise

Growing some vegetables at home or on the balcony lets you enjoy them as ornamentals and also eat fresh, tasty vegetables. In fact, growing vegetables isn't as complicated as you might imagine. These three vegetables, which you often eat in the kitchen, can be tossed straight into a pot when you can't finish them, and they'll grow very vigorously, and you'll even harvest a little surprise.

Sweet potato, the queen of vegetables. Sweet potato leaves taste soft and delicious, even better than water spinach (Ipomoea aquatica), and growing them is really simple.

If you have sprouted sweet potatoes at home, or sweet potatoes you can't finish, just toss them into a flower pot, or grow them hydroponically; they sprout especially abundantly. Pull off the sprouts and plant them in soil, and you'll have many pots of sweet potatoes.

There's another very simple method: when you buy sweet potato leaves to eat, keep the slightly older section of stem and stick it directly into the potting soil as a cutting. Water daily to keep it moist, shade it slightly, and within a week the leaves will stand up. It roots and survives incredibly fast.

You can regularly pinch off sweet potato leaves to eat; after pinching they grow again, and the growth is especially fast. By autumn, the pot is hiding a little surprise.

Ginger: if you have ginger at home that you can't finish, or ginger that has already sprouted, absolutely don't throw it away. Grown in a flower pot, it looks as beautiful as lucky bamboo (Dracaena sanderiana).

Even if it hasn't sprouted, place it in moist sand and within less than a week sprouts will emerge, then plant it directly into a flower pot. Cover with about 5 cm of soil and place it in a spot without strong light. Add some coal cinder or sand to the potting soil to increase air and water permeability.

The small sprouts grow taller and taller, the leaves grow more and more numerous, and eventually it grows even more lush and beautiful than lucky bamboo.

When harvest time comes, dig into the potting soil and inside are fresh, plump ginger roots.

Potato: generally, once a potato sprouts, people don't eat it. Using it to grow a potted potato is very simple.

But we cut it into three to four pieces, and if you happen to have an empty flower pot at home, just toss them into the potting soil. Don't water too much, to avoid waterlogging that causes the potato tubers to rot.

Keeping just a little moisture is enough. Place it in a spot with plenty of sunlight. Very soon many small sprout leaves will grow.

As long as the potting soil is loose and fertile, it can grow especially lush, and even produce light purple flowers.

After the flowers fade and the branches and leaves stop growing, cut off the stems, dig into the potting soil, and inside are many small potatoes. It's truly a delightful surprise!
